Hi,

I’d like to capture and process video frames using the Raspberry Pi High Quality Camera with Mathematica on the Raspberry PI 4 8GB.

The camera is connected to the camera port.

I am able to capture images and videos using the raspistill and raspivid commands, but not within Mathematica.

Output of $Version is:
12.0.1 for Linux ARM (32-bit) (June 23, 2019)

The following commands return no output:

$ImagingDevices 
Devices[]
FindDevices[]

ImageCapture[]
DeviceRead::raspiCamError: Error enabling camera-preview

Output of the linux command:
v4l2-ctl --list-devices
is:
bcm2835-codec-decode (platform:bcm2835-codec):
/dev/video10
/dev/video11
/dev/video12

mmal service 16.1 (platform:bcm2835-v4l2):
/dev/video0

Thank you,

Ed.
